The edit adds nothing to the question, but just adds formatting tags around what appear to be completely arbitrary places.

Should we be encouraging this type of edit? While I understand that some formatting helps (line breaks, paragraph breaks, indenting code) the reason of Good question!!Just made it little flashy!!Thanks!! adds nothing.

I'm more disappointed in the folks who approved nine bad edits (and those who cast approval votes on the twelve rejected edits). We will always have bad editors, and we're supposed to have a system to protect the site from them.

I definitely agree that it adds nothing to the question.

oh shoot! I rejected many of this guy's edits, I was furiously clicking "Approve" on the previous one and approved this by mistake. I wish there was a way to change the reviews' verdict. @Arjan, thanks for notifying me.

There was a user yesterday gunning for the Archaeologist badge, and proceeded to edit over 100 questions more than 2 years old by adding <!-- language: lang-js --> to all of the already-formatted code tags. They had enough reputation so that none of the edits needed approval.

I see exactly one suggestion that was actually helpful: stackoverflow.com/suggested-edits/343558 Nearly all of them have the description "Good question!!Just made it little flashy!!Thanks!!" Only seven of them were rejected. Urgh.

In borderline cases, reject as invalid. In the severe cases where they just spray code formatting randomly, reject as vandalism. Repeat until their will is broken.

Remember that people who have too many suggestions rejected are banned from suggesting further edits for a week--Hope is not lost! (Although ideally, suggestion bans would get longer each time to get one.)
